Hans Krasa

Three of the 20th century's greatest musicians all died on October 17, 1944 - and all at the hands of the Nazis. Czech composers Viktor Ullmann, Pavel Haas, and Hans Krasa all perished at Auschwitz (see videos of their music below); they were all taken there just three days after their final concert together on October 14, 1944 at the Theresienstadt concentration camp.

Brundibár, a children's opera that premiered during World War II, became both a symbol of hope and resistance and a Nazi propaganda tool. Now, Petite Opera, a small company in suburban Chicago, is reprising the opera, originally performed by Jewish children held in a concentration camp in occupied Czechoslovakia.
